Question
A computer sales associate makes 110 each day that she works and makes approximately 19 in commission for each computer that she sells. If she wants to make at least 338 in one day, at least how many computers does she need to sell?
Solution
To solve this problem, we first need to understand that the sales associate's total earnings in a day are a combination of her daily wage and the commission she makes from selling computers.
-
We know that she makes $110 each day she works, regardless of how many computers she sells.
-
We also know that she makes $19 in commission for each computer she sells.
-
She wants to make at least $338 in one day.
So, we need to find out how many computers she needs to sell to make up the difference between her daily wage and her desired earnings.
Here's how we can calculate that:
-
Subtract her daily wage from her desired earnings to find out how much more she needs to make in commission.
110 = $228
-
Divide this amount by the commission she makes per computer to find out how many computers she needs to sell.
19 ≈ 12
So, she needs to sell at least 12 computers in a day to make at least $338. Since she can't sell a fraction of a computer, we round up to the nearest whole number.
